Here is a race video between two supercharged E9X M3's running competing kits. One is a DCT (dual clutch transmission) M3 and that is the camera car with the ESS VT2-625 kit. The manual M3 has the VF-Engineering VF620 supercharger kit. This is a very evenly matched race as to be expected from two kits offering very similar performance. The manual has a slight jump and the DCT appears to reel it in somewhat although the race simply ends up basically a draw.

A very nice run but it would be great to see more than one race between these two. Regardless, it goes to show kits on the stock internals will basically end up in the same spot with fuel, boost, timing, etc., being the main differences especially among similar Vortech based superchargers. Despite what certain companies may say, the kits are very close to one another.

Camera car with DCT and ESS VT2-625 kit has a 91/100 mix. The VF car is also said to be a 91/100 mix.

Looks like the white car was actually faster, but he missed a shift and started a gear higher. (just what it looked like to me)

the Manual car is also carrying an extra 200 or so pounds. looks like it was shifted decently though. Like ive always said, DCT's only REAL advantage is consistancy. so what you are seeing is the REALWORLD result of .1-.2 seconds and maybe 1-2 mph difference(because of that .1-.2 TOTAL shift time) between transmissions

I think the shift time for DCT is 0ms - it's single clutch (SMG) that has a delay/there is a traction loss. I can dig up the quote from the Getrag engineer - it's on the board somewhere; I was curious, so I emailed him. There is no tractive loss between shifts, in other words no delay. On a manual car, it has to be greater than 0ms, it just depends on the driver.

Wrong. The blue car had wheels and a couple tools...less than 100 lbs. in the trunk.

In the first vid, I started in 3rd gear at 40 mph and the blue M3 started in 2nd gear. I also hit the rev limiter as I was pulling just before the finish line.

Did you guys not see the second race? We both started in 2nd gear and I put 5 cars on it.

The blue M3 dyno'd at 580 wheel on 91 octane and 603 wheel with some MS 109.
